Rapid chromatographic technique for preparative separations with moderate resolution
Abstract: (11) Potassium ferricyanide has previously been used to convert w'c-1,2-dicarboxylate groups to double bonds. See, for example, L. F. Fieser and M. J. Haddadln, J. Am. Chem. Soc., 86, 2392 (1964). The oxidative dldecarboxylation of 1,2-dlcarboxyllc acids is, of course, a well-known process. See Inter alia (a) C. A. Grob, M. Ohta, and A. Weiss, Helv. Chim. Acta, 41, 1911 (1958); and (b) E. N. Cain, R. Vukov, and S. Masamune, J. Chem. Soc. D, 98 (1969).
